To all whom-it may concern: i I are preferably tied together by connecting- Be it known that I, O'r'ro R. MJLKY, a bars 10, 10. ,As observed injFig. 2, the citizen of the United States, residing at front and rear wheels are out of alignment- Joplin, in the county of Prince lVilliam to obviate wear upon carpets'whenrolling 5 and State of Virginia, have invented certain the chair. g 60 new and useful Improvements in Combined The front and rear rocker-arms 1 and 5 Roller and Rocking Chairs, of which the are preferably keyed to the'shafts 6 and 7. following is a specification. The rear rocker-arms 4 are provided with This invention-relates to a combined rollan additional arm 11 carrying a vertically er and rocking chalr. v

'One of the objects of the invention is to actuate a. pivoted key 13. Arranged in the mount thechair uponrollers for convenience rear wheels 1 is an annular groove 14 adaptin moving around. v ed to receive a brakeband 15 provided with Another object of the invention is to proprojections 16, "16, of suflicient width to rei 15 vide a locking means for the rear wheels celvethe arm 11; as-noted in Fig. 7, when 70 when it is desirable to use the-chair as a the'plunger 1-2 isinits outer position, the rocker. r pivoted key 13 is in" such a position as not Another object of theinvention is to arto expand the brake-band 15.

The front and rear 'a'xles. a pair-of links22 pivoted to: the'fo'rward 110 substantially horizontal 'line,1"while the" rear shaft 6, the rear ends being provided with longitudinal slots 23 to receive a transverse rod 24- supported at its outer ends by the frame Surrounding this rod 24Lv is a tube 25 received between theouter ends of'the links 22. Collars 26 are arranged between the links 22 and the frame 3; and received on the outer threaded ends of the transverse rod 24 are adjusting nuts 27, whereby the link 22 may be locked in any position. As illustrated in Figs. 4 and 5, the slot 23 of such a length as to determine the forward and backward movement of the chair.

A foot-rest is provided preferably consisting of a substantially U-shaped frame 28, the rear ends of which are bent clownwardly at right-angles to the longitudinal portion, and upwardly at the lower ends. forming loops 29, which encircle the tierods 10. A pin 30 carried by the loop 29 is adapted to engage the notches 31 in the lower edge of the tie-rod 10, which determines the forward and backward position of the foot rest or support. A spring 32 carried by a suitable bracket 33 secured to the U-shaped frame 28 is adapted to bear against the upper edge of the tie-rods 10, thereby holding the pin 30 in engagement with the notches 31 in its forward or rear position.

A link 34. pivoted upon the transverse rod 35 carried by the U-shaped frame 28 is solidly secured at its upper end to a transverse bar 36 extending across the main frames 3, 3, the rod 34: being preferably slotted at its upper end to permit the chair assuming its extreme forward position, the slot 37 being of such alength as to permit thechair assuming its extreme forward position and to effect a vertical movement of the foot-rest when the chair is in an extreme inclined position,-thus permitting the user to assist by his feet in the rocking motion.

It will thus be seen that I have constructed a chair as above described, which is capable of general universal use, the rollers being of such a construction as not to interfere with the chair in its general use; and,"when desirable, some of said-rollers may be locked, whereby theuser may effect a rockingmotion of the chair. The rollers permit of itsimovement around the house with the least exertion.

It is obvious that, more or less slight changes might be made without departing fronrthe general scope of the invention; therefore I do not wish to be limited to the exact structure shown.

I claim:

1. The combination of a chair body, a supporting frame depending therefrom, a wheeled frame arranged beneath the supporting frame, rocker-arms keyed to the shafts of the wheeled frame and pivotally connected to the supporting frame, springs extending between the wheeled frame and supporting the supporting frame for resiliently supporting the chair body, and means for looking the chair against rocking movement.

2. The combination .of'a chair body, a frame I depending therefrom, a wheeled frame arranged beneath the supporting frame, shafts rotatably mounted in said frame, rocking-arms keyed to said shafts and pivotally connected to said supporting frame, and spring-guides pivoted to said shafts and received in suitable guides in the supporting frame adapted to receive springs for resiliently supporting the chair;

3. The combination of a chair body, a supporting frame depending therefrom, a wheeled frame arranged beneath the supporting frame, shafts rotatably mounted in a said frame, rocking-arms keyed to said shafts and pivotally connected to said supporting frame, spring-guides pivoted to said shafts and received in suitable guides in the supporting frame adapted to receive springs for resiliently supporting the chair, and means for locking one set of rocker-arms with one set of wheels whereby a horizontal movement of the wheeled-frame will impart a rocking movement to the supporting frame.

4. The combination of. a chair body, a supporting frame depending therefrom, a wheeled frame arranged beneath the sup porting frame, shafts rotatably mounted in said frame, rocking-arms keyed to said shafts and porting frame, spring-guides pivoted to said shafts and received in suitable guides in the supporting frame-adapted to receive springs for resiliently supporting the chair, means for looking the supporting frame and the wheeled frame together, against rocking pivotally connected to said sup? movement, and one set of rocker-arms to one set of wheels to prevent horizontal move ment of the wheeled frame.

. 5. The combination supporting frame depending therefrom, a wheeled frame arranged beneath the sup porting said 'rame, rocking-arms keyed to said shafts and pivotally connected to said supporting frame, spring-guides pivoted to said shafts and received in suitable guides in the supporting frame adapted to receive springs for resiliently supporting the chair, and means for locking the chair against rocking movement consisting of links pivoted to one of the shafts, and provided with slots at their outer ends, a transverse rod carried by the supporting frame, and adapted to receive the slotted outer ends of said links, means for clamping said transverse rod and links together. 6. The combination of a chair body, a supporting frame depending therefrom, a wheeled frame arranged beneath the sup-. porting frame, shafts rotatably mounted in of a chair body, a o

frame, shafts rotatably mounted in i said frame, rocking-arms keyed to said shafts and pivotally connected to said supporting frame, spring-guides pivoted to said shafts and received in suitable guides in the supporting frame adapted to receive springs for resilientlv supporting the chair, means consisting of links pivoted to one of the shafts, and provided at their outerends with slots, a transverse rod carried by the supporting frame, adapted to receive the slotted outer ends of said links, means for clamping said links and transverse rod together for preventing movement relative to the supporting frame and wheeled frame means for locking one set of wheels to one set of rocker-arms.

7. The combination of a chair body, a

supporting frame depending therefrom, a wheeled frame arranged beneath the supporting frame, shafts rotatably mounted in said frame, rocking-arms keyed to said shafts and pivotally connected to said suporting frame, said shafts and received in suitable guides in the supporting frame adapted to receive springs for resiliently supporting the chair, a foot-rest slidably connected to the wheeled frame, and means connected with, the sup porting frame for raising the foot-rest when the chair is in its extreme backward inclined position. v v
